The Medzev Hammer Mill is a technical monument featuring two hearths and a single water-powered hammer; it originally served to produce agricultural tools—such as hoes, spades, shovels, axes, nails, and horseshoes—using a now-historic manufacturing process driven by water power. Dating back to the second half of the 19th century, the facility has been managed by the Slovak Technical Museum since 1966. Currently, the Medzev hammer mill is listed in the Central Register of the Monument Fund under the name "Technical Museum Hammer Mill" as an immovable national cultural monument (registration number 4380).
The renovation of the Medzev Hammer Mill technical monument was a priority project for the Slovak Technical Museum between 2008 and 2010. It was funded by the state budget, utilizing priority financial resources from the Ministry of Culture of the Slovak Republic. After years of efforts to secure funding, the Slovak Technical Museum undertook a comprehensive restoration of the monument. The museum’s motivation was clear: to preserve unique regional traditions, given the historical significance of Medzev’s hammer mill production—which held great importance within broader historical, economic, and social contexts. Hammer mill production in Medzev endured for more than six centuries. During the era of the First Czechoslovak Republic—specifically in 1933—there were 95 operating hammer mills in Medzev; by 1955, 32 remained operational; and by 1960, work was being carried out only sporadically in four or five of them. Hammer mill production persisted until the 1960s, when this specialized small-scale ironworking craft was superseded by industrial manufacturing.
The techniques and technologies developed in the Medzev hammer mills were unique, not only within Slovakia but also on a European scale. The hammer mill currently managed by the Slovak Technical Museum—originally known as the "Town Hammer Mill"—once served as a training facility for local blacksmiths. It later belonged to the Tischler family, a dynasty of Medzev blacksmiths that had already established its prominence during the era of the guilds. The mill's final owner was Jozef Tischler; the Technical Museum in Košice (as it was then known) purchased the property from him in 1966.
Formulating a realistic program for the preservation, restoration, and—above all—utilization of industrial heritage sites is currently a major challenge in Slovakia, primarily because the state of the national economy allows for only very limited funding to be allocated to this sector. Thanks to funding allocated from the Ministry of Culture of the Slovak Republic’s budget between 2008 and 2009, the STM revitalized this technical monument *in situ* to a high professional standard, opened it to the public, and established conditions for the optimal cultural and educational use of the facility.
The reconstruction, which began in 2008, focused on restoring the production technology to working order. The first phase aimed to ensure the facility's functionality—specifically, exterior structural modifications, engineering coordination, and repairs to the building itself (including the perimeter wooden walls and entryways, the roof truss and shingle roofing, and the installation of a lightning rod and electrical wiring). A wooden water reservoir (sluice tank) was also constructed and installed.
The technical and processing equipment was put into operation in 2009. Interior structural work included the repair of hearths and bellows chambers. Subsequently, as part of the exhibition modernization, the water-powered hammer, grinding machine, and anvils were repaired, and new water wheels were manufactured. Exterior work was completed in 2010 with the restoration of the hammer mill’s water weir (reservoir) and the resolution of the water supply system. In the final phase, the Slovak Technical Museum (STM) outfitted the interior of the hammer mill—featuring restored production technology—with authentic tools, implements, and selected examples of Medzev-made products; these items were acquired in 2009 from the living descendants of the former mill owners. Inside the mill, the STM presents the machinery, tools, and products through a specialized exhibition dedicated to small-scale ironware manufacturing. As the site is a protected heritage object, care is taken to preserve the original setting of the immediate exterior as well, ensuring the highest possible level of authenticity.
Managed by the Slovak Technical Museum, the Medzev hammer mill serves as a "living technical monument," allowing visitors to witness the historical technology of forging tools using a water-powered hammer. Within the mill's distinctive atmosphere, visitors can appreciate the ingenuity and craftsmanship of the Medzev blacksmiths.
